Product Description The 16-Bit WS2812B 5050 RGB LED Circular Development Board is a high-brightness, individually addressable pixel ring designed for creative lighting and visual feedback. Each of the 16 LEDs contains a built-in WS2812B driver IC, allowing you to control the color and brightness of every single pixel independently using just one digital pin from your microcontroller. These "NeoPixel" compatible rings can be daisy-chained together via the "Data Out" (DO) pin, making them ideal for wearable electronics, circular status indicators, clock faces, and ambient light rings. The board operates on 5V and features a compact circular design that fits perfectly around camera lenses or robotic joints.

Key Features

  • Individually Addressable: Every pixel is programmable with 24-bit color depth (8-bit per channel), enabling millions of color combinations.

  • Single-Wire Control: Uses a high-speed one-wire protocol, drastically reducing the number of I/O pins required on your Arduino or ESP32.

  • Daisy-Chainable Architecture: Features Data Input (DI) and Data Output (DO) ports to connect multiple rings in a series without complex wiring.

  • Integrated Driver IC: The control circuit and the RGB chip are integrated into a single 5050 component, ensuring minimal board footprint and high reliability.

  • Built-in Power-on Reset: Includes an internal reset circuit to prevent random LED flickering during initial power-up

Technical Details

  • Communication Protocol: Uses a frequency-locked pulse width modulation (PWM) protocol with a transmission speed of 800Kbps.

  • Data Transmission Distance: Capable of transmitting data up to 5 meters between two points without any extra drive circuitry.

  • Scan Frequency: Features a high internal scan frequency of over 400Hz/s, ensuring flicker-free visual performance.

  • Color Uniformity: Every chip is factory-calibrated for high color consistency even at low brightness levels.

  • Cascading Capability: When 1024 pixels are cascaded at a refresh rate of 30 frames per second, the timing remains highly accurate.

  • Logic Level Compatibility: Works with 5V Arduino logic directly; for 3.3V devices like Raspberry Pi, a logic level shifter is recommended for long wire lengths.

  • Power Management: Each LED draws approximately 20mA per color (Red, Green, Blue) at full brightness; total ring draw can reach ~960mA at pure white.

  • Pin Configuration: Includes 4 solder pads: 5V (Power), GND (Ground), DI (Data Input), and DO (Data Output).

  • Thermal Design: FR-4 PCB construction with copper planes to help dissipate heat from the high-power LEDs.

  • Protection: Includes a built-in electric reset circuit and power-lost reset circuit.

  • Viewing Angle: Wide 120-degree light dispersion for even, diffused glow.

  • Firmware Support: Fully compatible with popular libraries like FastLED and Adafruit NeoPixel.

  • Brightness Control: Software-adjustable global brightness allows for power saving in battery-operated projects.

  • Mechanical Stability: The circular PCB is rigid and features standardized soldering pads for 2.54mm headers or direct wire attachment.

  • LED Spacing: Equidistant circular placement ensures a smooth ring of light when used with a 3D-printed diffuser.

Prototyping and Engineering Tips from Robogears

  • 9V Battery Use: Do not connect a 9V battery directly to the 5V pin. 16 LEDs at full brightness can draw nearly 1A, which will rapidly drain a 9V battery and potentially burn the LEDs. Use a high-current 5V Step-Down (Buck) Converter if using a 9V or 12V source.

  • 18650 Cell: A single 18650 cell (3.7V) can power the ring, but the LEDs will appear dimmer and the "Blue" channel may flicker. For professional results, use a 5V Boost Converter with your 18650 to maintain a rock-solid 5V rail.

  • IC & Capacitor Tip: Always place a 1000uF, 6.3V (or higher) capacitor across the 5V and GND pins at the power source to prevent the initial "on-rush" of current from damaging the first LED. Also, add a 330 to 470 Ohm resistor in series between your Arduino's data pin and the ring's DI pin.

  • Related Products: We recommend pairing this with our Arduino Nano, 5V 2A Power Adapters, and Diffused Acrylic Rings.
